Regarding the bird ingestion test, does the test make any distinction between fans of different diameters?
So, is it a one size fits all or do they factor in fan size?
The certification ingestion test FAR 33.77 factors in inlet capture area (generally requiring more birds).
The later generation engines (not the CFM56) increases the size of the birds vs capture area and yes as size goes up the quantity goes down just the same as mother nature per square foot.
